How to choose neje machine?
NEJE's primary machines currently include the NEJE max4, NEJE 3max v2, NEJE 3max, and NEJE 3 models.
1. (For Beginners)
If you are new to laser technology, setting up a DIY booth, customizing jewelry, or just starting out with laser machines and have limited knowledge in this field:
1.1. For hobbyist purposes, consider engaging in simple projects like carving and cutting thin materials during your leisure time. We recommend starting with the NEJE 3 model along with the NEJE E40 module for initial practices in creating straightforward pieces.
1.2. If your aim is to utilize the machine for a home-based business or fulfilling studio orders, potentially scaling up production for companies or factories, and you are committed to participating in NEJE's educational programs from novice to expert levels to grasp machine operations. Additionally, if you believe you have the capacity to troubleshoot common issues, opt for a sophisticated, high-performance machine that stays relevant for an extended period and caters to diverse business requirements. It is advisable to consider the Max 4 or 3max V2 models paired with the E80 module. The Max 4 E80 setup is widely preferred by home-based businesses and companies.
2. (Experienced or Expert)
If you have prior experience with laser engraving machines, 3D printers, and Lightburn software:
1.1. If you seek a machine that is exceptionally professional, sturdy, advanced, intelligent, and boasts high production efficiency, then you will indeed appreciate the features of the Max 4 E80.
The Max 4 comes with a unique motorized Z-axis,the functions of motorized Z axis are as follows:
——It can free your hands from manual height adjustments for each project.With simple configurations in the Lightburn software, the motorized Z-axis automatically moves to the optimal position.
—— This allows for simultaneously working on projects of varying thicknesses. Typically, once the module height is fixed, the material thickness remains constant, hindering the simultaneous processing of materials with different thicknesses. However, with the assistance of the motorized Z-axis, Lightburn software can be set to different material parameters, enabling the engraving or cutting of materials of different thicknesses concurrently.
——When paired with the E80 module, the Max 4 excels in cutting thick materials, curved surface engraving, layered engraving on irregular materials, deep engraving.
——With compatible plotter pen, you can sketch on various materials like paper/cloth for doodling, acrylic painting on canvas, sketching on fabric for customized clothing, or creating engineering drawings.
——With blade,it's just like a CriCut, you can cut heat transfer patterns, you can craft custom canvas bags, apparel, stationery pouches, makeup bags, backpacks, and even cut very thin soft materials, allowing full expression of your imagination.
The Max 4 machine has a working area of 750*460mm, expandable to 1030*750mm, ideal for users requiring extensive workspace or batch production. Its mainboard storage capacity has been upgraded to support stable transmission of large files and facilitate offline operations.
1.2. If you have budget constraints and do not require the functionality of plotter pen, blade, or the motorized Z-axis, then the 3max V2 is your optimal choice. Building upon the reinforced framework of the 3max, the 3max V2 ensures stability and durability. With a working area of 750*460mm, expandable to 1030*750mm, it suits users requiring extensive workspace or engaged in batch production.
1.3. Another model with a sizable working area is the 3max, providing a workspace of 750*460mm, expandable to 1030*750mm, perfect for users needing ample workspace or undertaking bulk projects. However, the frame of the 3max machine is not as robust as the 3max V2 or Max 4 models, being an older version. We have enhanced and upgraded the 3max V2 and Max 4 models. If your budget allows, we recommend opting for the optimized 3max V2 and Max 4 models.
